Could you give some information? The table would be really good, I’d be able to help you more efficiently. ☺️
Answer:
-22
Step-by-step explanation:
f(x) = 5x -7
substitute x = -3 into the equation as follows:
f(-3) = 5( -3) -7
= -15-7
= -22
It is A.
V=length x width x height
3x9=54
54x9=486
Answer:
Since the two angles are across from each other that tells us that they are equal in length, so we want to set them equal to each other
3x+50=6x-10, Now we want to solve it like a normal equation, get x by itself
First add 10 to each side
3x+50+10=6x-10+10
3x+60=6x
Now we want to subtract 3x from each side
3x-3x+60=6x-3x
60=3x
Now divide both sides by 3
60/3=3x/3
20=x
x=20
Hope this helps ;)
Step-by-step explanation:
This is the same as multiplying 10 by 28, which equals 280
